What Makes This Recipe So Good

• All the creaminess, half the heaviness. Greek yogurt and a splash of milk mimic the rich body of classic Alfredo without the mega calories.
• Protein-packed. Lean chicken breast plus Parmesan and yogurt turn this into a legit muscle-friendly meal.
• Weeknight-friendly. From pan to plate in about 30 minutes, and it reheats like a champ.
• No weird substitutes. Real Parmesan, real garlic, real flavor—just smarter proportions.
• Flexible base. Use regular pasta, whole wheat, or your fave high-protein noodle. It’s your bowl.

Ingredients

• 12 ounces fettuccine (regular, whole wheat, or high-protein)
• 1 pound boneless, skinless chicken breasts, thinly sliced
• 1 tablespoon olive oil
• 1 tablespoon unsalted butter
• 4 cloves garlic, minced
• 2 tablespoons all-purpose flour (or whole wheat pastry flour)
• 1 3/4 cups low-sodium chicken broth
• 1/2 cup 2% milk (or unsweetened cashew milk)
• 1/2 cup plain 2% Greek yogurt (room temp)
• 3/4 cup freshly grated Parmesan, plus more for serving
• 1 teaspoon kosher salt, divided
• 1/2 teaspoon black pepper, divided
• 1/4 teaspoon red pepper flakes (optional but recommended)
• Juice of 1/2 lemon (about 1 tablespoon)
• Fresh parsley, chopped, for garnish

Let’s Get Cooking – Instructions

1. Boil the pasta. Bring a large pot of salted water to a boil.

   Cook fettuccine until just shy of al dente. Reserve 1 cup pasta water, then drain.

2. Season the chicken. Pat chicken dry. Toss with 1/2 teaspoon salt and 1/4 teaspoon pepper.
3. Sear like you mean it. Heat olive oil in a large skillet over medium-high.

   Add chicken in a single layer. Cook 3–4 minutes per side until golden and cooked through. Transfer to a plate and tent with foil.

4. Build the flavor base. Reduce heat to medium.

   Add butter to the same skillet. Stir in garlic and cook 30–45 seconds until fragrant (don’t burn it—garlic drama is real).

5. Make a light roux. Sprinkle in flour and whisk for 1 minute to cook out the raw taste.
6. Whisk in liquids. Slowly pour in chicken broth while whisking to avoid lumps. Add milk.

   Simmer 3–4 minutes, whisking, until slightly thickened.

7. Yogurt + cheese magic. Remove pan from heat. Whisk in Greek yogurt until silky. Stir in Parmesan, remaining 1/2 teaspoon salt, 1/4 teaspoon pepper, and red pepper flakes.

   If too thick, loosen with reserved pasta water, a splash at a time.

8. Bring it together. Add cooked pasta and chicken (plus any juices) to the sauce. Toss over low heat for 1–2 minutes until glossy and coated. Finish with lemon juice for brightness.
9. Plate and flex. Top with extra Parmesan and chopped parsley.

   Taste and adjust seasoning—more salt, pepper, or lemon as needed.

Storage Tips

• Fridge: Store in an airtight container up to 3 days. Add a splash of broth or milk when reheating to revive the sauce.
• Freezer: Not ideal due to yogurt separation, but doable. Freeze up to 2 months.

  Thaw overnight in the fridge and reheat gently with extra liquid.

• Reheat: Low heat on the stovetop with 1–2 tablespoons water or broth, stirring until creamy again. Microwave in short bursts, stirring between.

What’s Great About This

• Sane calories, real satisfaction. You’re getting the comfort of Alfredo without the brick-in-your-stomach aftermath.
• Balanced macros. Protein from chicken and yogurt, carbs from pasta, and just enough fat to carry flavor.
• Smart brightness. Lemon and pepper flakes lift the richness so it doesn’t feel heavy. Your palate gets flavor, not fatigue.
• Meal-prep friendly. Holds up in the fridge and reheats without turning into glue—just add liquid.

  FYI, that’s the pro tip.

Don’t Make These Errors

• Cold yogurt = curdled sauce. Let the Greek yogurt come to room temp and take the pan off the heat before whisking it in.
• Skipping the roux. The tiny bit of flour stabilizes the sauce so it stays silky. Don’t rely on yogurt alone.
• Overcooking the chicken. Thin slices cook fast. Pull them when just done to keep them juicy.
• Forgetting pasta water. This is your insurance policy for perfect consistency.

  Keep at least 1 cup on standby.

• Using pre-shredded cheese. It’s coated with anti-caking agents and won’t melt as smoothly. Grate your Parmesan—worth it, promise.

Mix It Up

• Veggie boost: Toss in steamed broccoli, peas, or sautéed spinach. Mushrooms?

  Absolutely.

• Different proteins: Swap chicken for shrimp (cook 2–3 minutes per side) or rotisserie chicken for speed.
• Herb it up: Add fresh basil, chives, or a pinch of Italian seasoning with the garlic.
• Gluten-free route: Use GF pasta and a 1:1 GF flour blend for the roux.
• Extra creamy (still light): Stir in 2 tablespoons light cream cheese with the yogurt for luxe vibes.
• Lemon-pepper twist: Add 1 teaspoon lemon zest and extra black pepper for a brighter profile.

FAQ

Can I make this without yogurt?

Yes. Swap the yogurt for 3 ounces light cream cheese or 1/2 cup evaporated milk. The texture will be slightly different but still creamy.

Adjust salt and lemon to taste.

What pasta shape works best?

Fettuccine is classic, but penne, rigatoni, or rotini grab the sauce like champs. If using chickpea or lentil pasta, undercook by 1 minute to avoid mush.

How do I prevent the sauce from breaking?

Keep heat moderate, whisk constantly after adding broth and milk, and remove from heat before adding yogurt and Parmesan. If it tightens too much, add warm pasta water a little at a time.

Is this kid-friendly?

Totally.

Skip the red pepper flakes or add them at the end for the adults. Creamy pasta is basically a universal love language.

Can I cut the sodium?

Use low-sodium broth, reduce added salt, and rely on lemon and herbs to amplify flavor. Fresh Parmesan has salt, so taste as you go, IMO.

Can I cook the chicken ahead?

Yes.

Cook and slice up to 3 days ahead. Warm it gently in the sauce so it doesn’t dry out, adding a splash of broth if needed.

What if my sauce is too thin?

Simmer 2–3 extra minutes before adding yogurt, or whisk in an extra teaspoon of flour with a splash of milk and simmer briefly. Parmesan also thickens as it melts.

What if my sauce is too thick?

Loosen with reserved pasta water, milk, or broth a few tablespoons at a time until it’s glossy and coats the noodles without clumping.
